[racket] crash possibly related to sqlite

Sometimes you can stress the VM by throwing in calls to
`collect-garbage`, possibly in anything that acts like a callback, or
possibly in a thread that forces a collection every few seconds.

But, crashes after a lot of numerical work with SQLite work much
earlier... I'm not so sure. I guess you can't get it to crash by
interrupting the numerical part early?

I would try running myself even if it takes hours. Sometimes, I can get
information out of a crash that lets me create a different program that
crashes quickly.
